Need An Oil Breather Suggestion Options

[kenshapiro2002]

My oil breather hose just dead ends in my cooling "well". What a decent, affordable (like $50 or less) breather box that I can just vent into the atmosphere of the engine bay, pulling off the oil and not throwing it into my engine?

Heads were not vented on '75-'76 engines for tighter emissions control.

You ought to spend some time in the library reading and you may find the reason crankcases / heads are vented, but since you haven't ....

1.) The spinning crankshaft assembly creates a hell of a storm inside the engine and whips up oil, entrains air with a wet sump system. For years, crank scrapers and windage screens have been used to quell the storm.

2.) Rings do not seal perfectly. There is always some blowby present pressurizing the case.

3.) Adding the Empi or whatever type breather or just a can has no provision to drain the oil back to the case where it belongs.

4.) The system that Chris makes appears to be somewhat modeled after a dry sump tank .... inlet at top, probably with baffles and a screen to break the air entrained in the oil out so that it drops to the bottom of the tank and dribbles back into the case.

5.) You can drill your heads in the car ... use heavy grease on the drill and tap and it will capture the shards. You can use a threaded hose barb in this manner.

5.5.) Vacuum to pull the oil vapors / droplets into the engine to be burned can be obtained by tapping the top or bottom of the carb air cleaner and routing the vent hoses to the air cleaners.

6.) If you decide to vent the valve covers, the vent mu be in the upper portion of the cover as the rocker box can run about 1/2 full of oil. You braze the fittings onto the cover unless you can find a bulkhead fitting that will work.
